This is the old, iperf 2 code base, which is no longer maintained by ESnet. ESnet's primary development efforts have moved to a completely-rewritten version of iperf (iperf3), which is hosted on GitHub. You can find it here: http://github.com/esnet/iperf.

In the meantime, a third party has taken over maintenance and feature development of iperf 2. That project is hosted here: https://sourceforge.net/projects/iperf2/.

Iperf was developed by NLANR/DAST as a modern alternative for measuring maximum TCP and UDP bandwidth performance. Iperf allows the tuning of various parameters and UDP characteristics. Iperf reports bandwidth, delay jitter, datagram loss.
